(I´m currently using OpenCart 1.5.6.4.)
Every time a purchase is made, it is not synchronized with the store, so it does not generate reports or any specific information about the purchase. Why can this happen? http://tiendavirtual.mdc.org.co/tiendavirtual
The reports were working until 5 months ago, on 04/05/2017

Please help!! this is very important, would really appreciate your support!!
